Neuroscientific evidence about the distinction between short- and long-term memory

What have neuroscientific techniques contributed to the development of psychological theory about short- and long-term memory? We argue that the contributions have been varied: In some cases, data about brain mechanisms have been vital to the advancement of psychological theory; in other cases, neuroscientific data and behavioral data from normal participants have made equal contributions; and in yet other cases, the data from neuroscientific approaches have actually led psychological theory astray. We illustrate these various contributions by focusing on the relationship of short- to long-term memory.
